We have put a fair amount of effort into reducing the impact of our staff canteen in our office. One part of this is introducing separate food waste and recyclables bins. However many canteen users use the wrong bins, with significant amounts of all types of waste going into all three bins.
The bins are well signposted but people seem either to not read or otherwise disregard the signs.
Is there any research on how to encourage waste sorting, or failing that does anyone have anecdotal evidence on effective ways to improve this situation?
